Princess Diana was very close to both of her sons. But whenever they are posing for photos, it seems that the late royal is more affectionate towards Prince Harry.

Prince William and Prince Harry’s personalities couldn’t be more different from one another. The former is more serious, while the latter is the joker of the royal family. Prince Harry is also very touchy-feely as made evident by how he displays his affection towards Meghan Markle while they are out in public.

In an unearthed photo, Princess Diana is sitting on a couch beside her youngest son. The doting mom is smiling from ear to ear while holding Prince Harry’s hand affectionately.

Behind the two royals are Prince Charles and Prince William. Prince Charles looks happy in the photo, but Prince William has a slight smirk on his face.

In another throwback photo, Prince Harry is leaning on his mom’s shoulder. Prince William, on the other hand, is just sitting close to Princess Diana.

When Princess Diana was still alive, she made sure that Prince Harry would never feel that he’s loved less or that he’s less important compared to his older brother. As such, Princess Diana showered the Duke of Sussex with more love and affection.

On one occasion, Prince Harry came home and told Princess Diana that he always felt left out whenever he goes to the Buckingham Palace. After all, the senior members of the royal family always want to be around Prince William. This is because the Duke of Cambridge will become King one day.

And even though Prince William was more serious compared to Prince Harry, Princess Diana still exerted an effort to try to make her eldest son laugh. The Princess of Wales used to send Prince William naughty cards while he was at boarding school.

“She had a very cheeky sense of humor. She was a massive card writer and she loved the rudest cards you could imagine,” Prince William said.
